Hey Guys, I am renovating an big Viscount caravan and I am replacing some walls. I have come across this powdery off white insulation and I want to know if it is asbestos or toxic before I continue. Does anyone have an idea as to what material it is? ibb.co/jy40Dsf

From the Viscount thread in this forum - August 73: News Report..."Viscount Caravans, spurred on by the sales success of the new 1973 range with updated interiors, has recently developed a new foam insulation process. Appearing much the same as shaving cream, it is sprayed between the inner wall and the aluminium external cladding. The material sets into a harder substance and has remarkable properties. Not only does the insulation reduce summer temperatures inside the caravan by 20 per cent, but it improves heating in winter. It also has sound deadening advantages. A reassuring element is the fact that the material is fireproof and won't absorb moisture or mildew."
From various Viscount articles during the mid 70s - "a lightweight, fireproof spray on foam insulation" "chemically designated urea-formaldehyde, low density and non-toxic." "vermin and fire proof."
A few owners have had it tested after finding it had been reduced to a powder in their walls, it was found to be negative for asbestos but as mentioned above, does contain formaldehyde.
